NVIDIA/Mellanox MC220731V-025 Compatible 56G QSFP+ Ethernet Active Optical Cable, 25m (82ft)

This MC220731V-025 compatible AOC cable provides a High-Speed direct connection for NVIDIA/Mellanox equipment in a fixed 25m (82ft) configuration. The QSFP+ to QSFP+ assembly integrates both ends and the cable, giving data-center designers one defined product to evaluate for reach, rack layout, airflow and host compatibility.

Cable Construction and Routing

This assembly uses OFNP jacket, minimum bend radius 30mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

Position Within the Length Range

MC220731V-025 occupies the middle of this family between MC220731V-020 at 20m (66ft) and MC220731V-030 at 30m (98ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Data-Center Design and Airflow

Select the assembly by both reach and rack layout. A direct connection removes separate module-and-patch-cord interfaces, but it still needs a bend-safe pathway and clear connector access. Keep cable bundles from blocking front-panel airflow, account for the listed interface power where applicable and choose a length that supports maintenance without leaving an unmanaged coil. For this assembly, the minimum bend radius is 30mm; the jacket material is OFNP.

Network and Protocol Considerations

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include 56G InfiniBand , 4x FDR, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.

Integrated Optical Assembly

The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.

Length Selection and Installation Planning

Extended reach changes the installation checks for MC220731V-025. Confirm that 25m (82ft) follows the intended route without tension, then verify that intermediate supports do not squeeze the jacket or hide the connectors behind adjacent cables. Both hosts must still match the stated interface and lane configuration. Within this family, MC220731V-020 is shorter at 20m (66ft), while MC220731V-030 is the next longer choice at 30m (98ft); comparing those two boundaries helps avoid both tension and unnecessary slack.

Quality Assurance and Packaging

Each cable receives connector inspection and a functional link check before it is coiled with bend-safe slack and packed. Protective materials shield the connector housings during transport. Rack or project labels are available to keep length, part number and installation destination aligned. Neutral packaging and customer-specific packing documentation are available on request.

Ordering Information

Provide the OEM reference, HT part number, fixed length and quantity, together with the intended host interfaces. Rack-based quantities and packaging instructions can be included for larger deployments. Other lengths are separate products and should be entered on their own order lines. Keep MC220731V-025 associated with 25m (82ft) throughout the order and receiving record.

NVIDIA/Mellanox Compatibility and Factory Testing

Compatibility confirmation combines host identification with actual link establishment and diagnostic checks. The assembly is prepared for the stated OEM reference rather than selected only by connector shape. For a new data-center deployment, the equipment model, port mode and software release provide the most useful basis for a pre-order review. Where supported by the host, receive activity and diagnostic indications are reviewed together with the established link.

Frequently Asked Questions

Is this an original NVIDIA/Mellanox cable?

No. It is an HT-manufactured compatible alternative for equipment that specifies NVIDIA/Mellanox MC220731V-025.

What details assist a compatibility review?

Provide the equipment manufacturer, model, port type, hardware revision and software release, together with the OEM reference, required length and quantity.

How should an unused assembly be stored?

Protect both connector ends, keep the cable in a loose bend-safe coil and retain its part-number label so the length and compatibility identity remain traceable.

Can different brands be connected with the same assembly?

Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.

Shipping and Lead Time

Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
